the fastest 40 yard dash is 4.24 seconds but it would be easier to ask your college alg teacher
The 4.24 40 is equivalent to about 19.23 mph, computed as follows:
one hour equals 3600 seconds. Divide the 3600 by the 4.24 to get 849 (theoretical) times that 40 would be run in one hour. Multiply the 849 times 120 feet to get total feet traveled in that hour (101,887). Divide the 101,887 by the number of feet in a mile (5,280) to get 19.23.
Keep in mind that is the average speed over the 40 so when the combine shows speeds in excess of that, they are calculating the highest speed during the run, with zero being the start and the max near the end.
Running a 40-yard dash in 4.2 seconds equates to a pace of 19.48 miles per hour.
Oh, dude, you're hitting me with the conversions now? Alright, alright. So, a 9.5-second 100-yard dash is approximately equivalent to a 10.97-second 100-meter dash. But hey, who's really counting, right? Like, just run fast and hope for the best.
To convert from square yards to square miles, multiply by 3.228E-07.
1 miles = 5280/3 yards = 1760 yards. 50 yards / 1760 yards/mile ~= 0.02841 miles 6.6 seconds / 3600 seconds/hour ~= 0.001833 hours 0.02841 miles / 0.001833 hours ~= 15.5 miles per hour
1 yard = 0.000568181818 miles
3.5 seconds in the 30 yard dash equals 17.53 miles per hour.
Running a 40-yard dash in 4.2 seconds equates to a pace of 19.48 miles per hour.
To convert a time in seconds to miles per hour, you first need to convert the distance to miles. 40 yards is approximately 0.02273 miles. Then, you can calculate the speed by dividing the distance by the time in hours. For 4.3 seconds over 40 yards, the speed is approximately 1.25 mph.
Hines Ward's 40 yard time is 4.55 seconds.
The sprinter's speed is 22.53 miles per hour.
